When I add an image gallery to an article, the article image displays twice within the gallery lightbox. When the image is removed from the gallery section, the article image is removed as well. Is there any workaround to this problem?

Is it also possible to show all gallery images only in the lightbox which is evoked from the article image? In that case only the article image is shown at the beginning of the article and all other gallery images would not been shown at all.

I believe the lightbox takes its gallery in the pop up from all the images present on the page but I don’t think there is a way to add in a full gallery only in the pop up if the images are not on the page.

As for the main issue, can you link to your site so we can take a look at what might be happening?

The first and second image of the gallery is identical. The first one is the article image and the second one part of the gallery. If I remove the picture from the gallery, the article image is removed as well. There seems no way to just show the article image once inside the gallery.

This is only a partial and temporary workaround to this problem as the extra gallery image item inserted from the Featured Media also swaps the ALT text with CAPTION and omits the image TITLE at the bottom.
